To all whom t 27u13/ concern:

Be it known that I, Fonns'r V. DETWILER, a citizen of the United States, residing -at Pottstown, in the .county of Montgomery and State of Pennsylvania, have invented certain new and usefulImprovements in Hydrocarbon Burners, of which the following is a specification.

This invention relates to improvements in hydrocarbon burners for boilers, furnaces, and the like, and one of the objects of the invention is to improve and simplify the construction thereof and reduce the cost of manufacture.

A further object is to provide an improved burner of this character which will be of a sectional construction and having improved means for securing the sections together.

A further object is to provide -an improved means for supporting the burner whereby it may be arranged at any desired elevation in the fire pot of a boiler orL furnace.

To the attainment of these ends andthe accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts, hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this invention and in which;

Figure 1 is a side elevation of an improved burner of this character constructed in accordance with the principles of this invention.

Figure 2 is a left hand end elevation of Figure 1.

Figure 8 is an irregular sectional view taken on line 8 8, Figure 5.

Figure 9 is an enlarged det-ail section-al view showing one manner of packing `be tween the feinte,

Referring more particularly to the drawings the burner body is of sectional construction comprising a bottom portion 10 'and upper portion 11. The bottom portion 1Q is of a sectional construction and is secured together in any suitable manner pref 'erably by means of flanges l2 on the inside ofthe section and fastening bolts 13 assing through thev flanges. The bottom 1s yof a frusto-conical configuration and is provided with laterally projecting portion 14 terminating preferably in a priming pan 15 formed integral therewith.

.The upper portion 11 is also of a sec-- vtional construction and is of a frusto-conical configuration of a size to encompass and be spaced from the portion 10. The wall of the portion 11 is provided with burner slots 1G preferably arranged vertically therein and the upper. portion is adapted to rest upon the laterally projecting portion 14 of the bottom, and may, if desired, be rotated about the bottom portion. The sections of the top port-ion 11 are held together by means of suitable flanges 17 and arranged on the abutting edges, and through which flanges suitable fastening bolts 18 pass.

The top .19 of the bottom portion 10 is provided with an opening 2O therethrough and around the opening is provided a seat 21 in which a flange 22 of a collar 23 is adapted to be seated, and this collar 23 is adapted to be held in position by means of `suitable fastening bolts 24. The collar is provided with internal screw threads and engaging the threads is a threaded end of an inlet pipe 25 which discharges into the chamber formed by the portions 10 and 11 of the burner to convey the vapor into the burner and which vapor passes through the burner openings or slots 16 to be ignited. The other end of the pipe 25 is open as at 26 and the parts thus formed may be supported by a base 27 to which the pipe 25 may be secured in any suitable manner such as by means of a fastening bolt 28 passing through a flange 29 on the pipe.

Encoinp a ssing the burner body thus formed is a vaporizing pipe 30 which may be supported in any suitable manner such las by means of brackets 31. To the outlet end 32 of the vaporizing pipe 31 is connected a nozzle 33 which discharges into the opening i26 of pipe 25 and the nozzle provide with a valve 34 for controlling the same.

' An indicator 35 may also be provided for The inlet end 39 of the pipe 30 is connected with a valve casing 40 and this valve casing is provided with an inlet passage 41 to which is connected a supply pipe 42 Which receives its supply from a supply tank 43. `Pressure is exerted in the tank 43 in any suitable manner such as by means of a pump 44 and the fuel is supplied from the tank 43 through the pipe 42 into the valve casing 40 and is controlled by a valve 45 having an indicator 46.

The valve casing 40 is provided With a passage 47, one end of which has communication With the inlet end 39 of the pipe 40 and is controlled by a valve 48 provided With an indicator 49.

j The other end of the passage 47 is connected with a priming pipe 50 and is controlled by a valve 51 having an indicator 52. vrIlhe priming pipe 50 is seated in the priming panA 15 and extends around the base of the burner beneath the vaporizing pipe 30. The priming pipe is provided with openings 53 in its bottom to deliver fuel to the priming pan. The specific construction of this valve mechanism, although herein fully4 described, will constitute the subject matter of a separate application.

To start the burner all that is necessary assuming that suflicient pressure is in the tank 43 is t0 open the valve 45 to permit the fuel to How into the opening 41 and into the passage 47. The valve 51 is then opened to supply the priming pan with fuel. Vhen sufiicient fuel is supplied it is ignited and the valve 51 is closed. The ignition of the fuel in the priming pan 15 heats the generating pipe 30 and when the pipe 30 is sufficiently hot the valve 48 is opened to permit the fuel to How into the pipe 30 Where it will be vaporized and will be deliveredfrom the pipe 30 through the nozzle 33 into the pipe 25 and into the burner bottom Where it will be ignited at the openings 16.

, In order toprovide a means whereby the elevation of the burner may be varied in the fire pot a suitable adjustable support may be provided and embodies an upright which is pro-vided With threaded extremities. One extremity has engagement With a collar 55 that 'is seated in a sectional base 56 upony which the body of the burner rests.

p the sections of the base 56 being secured together by suitable fastening devices 57. The other end of the upright has threadedgengagement with a collar 57 seated a tion but embodies sections 62 having a deflecting surface 63 and the sections are secured together by means of abutting ears 64 through which a fastening device 65 passes.

The defiector thus formed is provided with an opening 66 through its body and the deflector is adapted to engage and rest upon the top of the outer section 11 of the burner, so that theflanges 17 of the sections will stand Within the opening 66. Vhen the deflector is in position it will be manifest that the clamping of the ears 64 together Will serve as a means for causing the.

sect-ions of the deflector to grip the top of the section 11, though when it is desired the deflector may be .readily removed.

If desired, and in order to provide an additional securing means for the pipe 25 (see Figure 8) there may be provided vspaced ears 67 on the base 27 adjacent the point where the entrance opening 26 of the pipe 25 is located'and fastening screws 68 may be provided to pass through ythese ears to engage the outer surface of the end of the pipe 25.
